This is the main dialog, showing a NOTAM being displayed.
The Category, Subject and Condition are taken from the ‘Q’ line which is now provided by AIS.
This enables more accurate classification and filtering than by using the previous method of analysing the text.
The position and radius are also taken from the ‘Q’ line. These do not, however, accurately reflect the area covered by the NOTAM if it is not an actual circle.
To get round this, Spine also extracts any coordinates found in the text to build a list of points defining an area.
This is particularly important for accurate plotting, or when using
Spine to generate an OpenAir or TNP file for display of NOTAM boundaries on a PDA in flight, where showing circles instead of actual areas is not useful.
Also displayed is the distance and bearing from the home airfield (in this case RIV).
The data fields are shown in black, indicating that this NOTAM will be included in the output. Deleted entries are colour coded as shown.
